There are 27 bones in a human hand. 8 carpals, 5 metacarpals, and 14 phalanges (each of your fingers has 3 phalanges in them – proximal, middle, and distal. However, there are only two phalanges in your thumb, proximal and distal.)
The human hand has 27 bones, 14 of which are the phalanges (proximal, medial, and distal) of the fingers. The metacarpal is the bone that connects the fingers and the wrist. Each human hand has 5 metacarpals.
- 14 phalanges; proximal, medial (all except the thumb), and distal in the fingers.
- 5 metacarpals, I, II, III, IV, & V in the hand.
- 8 carpals: scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, and trapezium in the wrist.
One-fourth of all of your bones are in your hands. And half of all your bones are in your hands and feet, since the feet have another 52 bones. These are:
- The distal phalanx, carrying the nail,
- The middle phalanx and
- The proximal phalanx.
Sesamoid bones are small ossified nodes embedded in the tendons to provide extra leverage and reduce pressure on the underlying tissue. Many exist around the palm at the bases of the digits; the exact number varies between different people.
Bones don’t bend. Imagine that your finger had only one bone. It couldn’t do very much. You could poke things, but that’s about it. Luckily each finger has 3 bones, so we can bend them to do thinks like type, write, and play instruments
